Spurious GCC warnings

[John Maddock]

Boost.Math is getting an annoying warning from Fusion, for example:

#include <boost/math/special_functions/gamma.hpp>

leads to:

In file included from ./boost/math/special_functions/erf.hpp:1078,

When built with g++ 4.3 and -Wall -Wextra.

Cheers, John.

Simply replacing the line

        vector0(Sequence const& seq)

by

        vector0(Sequence const&)

would fix this.

Fixed in [62854].
